Application filed August 16, 1907. Serial No. 888,817.

To all whom it my concern:

. Be it known that 1, AUGUST SUNDH, a

citizen of the United States, residing at Yonkers, in .the county of Westchester and State-of New York, have invented a new and useful Improvement in Ash-Hoist Construction, of which the following is a specifi cation. v My invention relates to hoisting mechanism especially adapted for elevating ash cans or other receptacles from a compart;

ment formed beneath a sidewalk up through aniopening in the walk and depositing them at the curbstone. 1 5- One of the objects of the'invention is to provide a'device of this characterin which the receptacle is carried upwardly through the opening in the walk and automatically guided and placed on.the-walk atone side of the opening.

Other objects of the invention will appear hereinafter, the novel combinations of elements being 'set forth in the appended claims.

Referring to the .di'awing,- in which is shown a construction embodying my invention, Figure 1 is a sectional'elevation through a sidewalk and compartment ;in which the hoisting mechanism is installed, and" showingthe mechanism in operating position; Flg. 2 is a plan view of parts shown in Fig. 1; and Fig. 3 is a sectional view (on an enlarged scale ofthe hoistingrope or cable and portions of the friction pulleys engaging the rope.

The hoisting device is installed in a com-e p'artme'nt 1 located beneath a sidewalk i2.

The portion of the walk 2 over the-compartment-l may be supported by the horizontal framework 3 carried by the foundation wall 4 of a building and vertical $1pports 5-. The compartment 1 communicates through a door or passageway 7 formed in the wall'4 with a basement or cellar from which the ashes are to be removed.

The hoisting mechanism comprises a supporting member A which is movable up and down through an opening 8 formed in the sidewalk. The supporting member consists of a vertical rack bar 10 and a substantially horizontal or laterally extending, arm 11 at thetop of the rack bar. The arm 11 is swiveled on a vertical extension 12 of the rack bar, and-may be held against rotation by a removable pin 13 extending through the arm 11 and the extension 12; The rack bar 10 is held in position and guided in its. vertical movements lay-guide brackets l4.and 15 secured respective to the side of the opening 8 andthe 'frame work 3 immediately below the opening 8. The rack teeth 16 formed on thebar'10 mesh with a worm 17 on theupper end of a.

worm shaft 18. The shaft 18. has bearings in the bracket 15 above and below the worm 17, and is also held thereby against lon tudinal movement. The lower end. of t e rod 18 is provided with a hand wheel 19, by means of which the rod 18 ay be rotated to lift or lower the rack bar. The lower end of the rack bar is formed with a bearing sleeve 20 surrdunding. the rod 18 and slidable thereon as the rack bar moves up and down. The lower end of the rod 18 is held against any'lateral movement by the bearing 21.

Although the construction just described provides a convenient means for lifting and lowering the supporting member A, other forms of lifting and lowering mechanism might obviously be adopted.

The ash can or other receptacle R is lifted and lowered by means of a hoistingrope or cable 22, provided at one end with a hook 23 to hold the hail of the receptacle R. The

rope 22 extends from the'receptacle' up with-a large gear wheel 28. Secured to the gear wheel 28, or keyed to the same shaft for rotation therewith, is a drive sheave 29 havin a groove 30 in its periphery to receive 51c rope 22. The motor and drive gear 28 are carriedby a plate 31 bolted or otherwise secured to the'sicle wall of the passageway 7. This forms a convenient location for the motor in a position where the operator can observe the operation of the hoisting mechanism and can watch the receptacle during its entire travel. A controlling lever 32 is fulerumed at its upper end by a pivot 33 to the plate 31 and has a handle 34 at its lower end. The lever 32 carries a pressure sheave 35 a short distance below the pivot 33, the sheave 35 being opposite and in the same plane with the drive sheave 29, as indicated in Fig. 3. The'sheave 35 isalso provided with a shallow circumferential groove-36 to receive the rope 22. Pivoted on the lever 32 concentrically with 'the sheav'e 35 is a depending arm 37, provided at its lower end with an extension 38 opposite the lower end of the lever 32. Between the lever 32 and the part 38 a coil spring 39. A cam 40, pivotedona stationary plvot 41 and provided with'a handle 42,.

is mounted to engage the outer surface of the'part-38.

A. pair of inclined guide rails 44 are located in the compartment 1 and extend from the floor 6 of the compartment 1 to the edge of the opening 8, the upper'ends of the rails being-substantially even with the surface of ,the walk. These rails areipreferably made in the form of angle irons placed parallel and spaced apart a suflicient distance to journaled in the edge of the walk, against which the receptacle bears as it is leaving the rails. The arm 11 when held by the pin 13 extends from the rack bar 10 at an angle as shown in Fig. 2 such that the pulley 24 is .in a vertical plane midway between the rails 44, the length of the arm being such that the rope 22 extending from the receptacle to the pulley 24 is substantially parallel with the guide rails; When the hoisting mechanism is not in use, it is retained in the compartment 1, the entlre mechanism being lowered beneath the surface of the walk .and .the'

opening 8 is closed by a hinged door or cover 47.

The operation of the hoisting mechanism will now be briefly stated.

Assuming that the supporting frame A- has been raised to operative position as shown, that an ash can-R has been placed vat-the foot of the inclined guide rails, and ,th'al t',t li e hook 22 has been attached to the re-, ;-r-.ceptacle, let theswitchS be closed to cause so the electric current to flow through the motor to rotate the same and the drive sheave 29 in a counter-clockwisedirection, as indicated byfthe arrow. If the'operator now moves the handle 34 to the right the sheave be pressed. against the rope 22. This holds the rope in frictional engagement with the drive sheave 29, and the rope is driven by the sheave 29 and fed through between the same and the. sheave 35; As the ash can leaves the rails it swings outwardly over the walk to thepo'sition shown indotted lines. The operator now releases the controlling lever 32 and the ash can settles by its own weight on to the walk; After the can has been emptied it may be placed in position to permit it to descend by gravity whiledrawi-ng. the rope 22 back to position for another operation. To prevent too sudden descent the wheel 35 may be moved to hold the rope against the sheave 29, now held stationary by the motor brake, thus compelling the rope to be frictionally retarded by slipping over the sheave 29. Instead of op- ,erating the lever 32 directly by means of the handle 34, the cam 40 may be turned about its axis to move the part 38 to the rightwhich will compress the spring 39 and operate through the lever. 32 to hold the 1 sheave 35 against the rope 22 with a yielding pressure varying with the extent the cam is turned. By this means less effort is required to control the. friction clutch. I

If it is desired to lift the ash can or other article without the use of the guide rails, the pin 13 is removed and the arm 11 swung to the position shown in dotted lines in Fig. 2 in which position the load can be lifted vertically through the opening in the walk.

tion embodying my invention in a practical form, but it is obvious that various changes in details of construction and arrangement of parts nnght be made by those skilled in the art without departing from ,the spirit and scope of the invention, and I wish therefore not to be limited to the precise construction disclosed.

What I claim as new and desire to secure by'Letters Patent of'the United States is 1. In hoisting mechanism, the combination with a rope or cable, and means carried thereby for holding a receptacle, of a pair of parallel inclined guide rails spaced apart to support and guide the receptacle, a direction li eav'e over which the rope or cable passes, and means for supporting the sheave in a position in which the cable extending from the sheave to the receptacle is substantially parallel with the rails.
